I have learnt that a word can have many meanings as we interpret words primarily subjectively. With that said, the word “Tart” paired with the fruit means various things to me like bitter, unpleasant or unwanted but also mysterious and ambiguous in terms of overwhelming but potential for beauty at the same time. It reminds me of situations or even people I may come across as some are straightforward while others are contradictions.
All in all it’s all about interpretation and how I choose to view a term/food/situation/person depends on the context and current outlook at the time or mood. Too heavy maybe but thought provoking don’t you think?
